The popular characters reportedly went up to the unnamed child and suddenly started using sign language — a reportedly unplanned moment that left him visibly elated, according to Good Morning America.

A video of the moment shows Mickey and Minnie kneeling down and telling him, “I love you” and “It’s nice to meet you,” leading the child to become so overjoyed that he gave both characters an impromptu hug.

The encounter was shared on Facebook by Oliver Crest, a group that works to prevent child abuse. Watch it below:

A spokesperson for Olive Crest said that the little boy isn’t typically a hugger and the fact that he embraced both Minnie and Mickey “spoke volumes to the joy he felt.”

“The child was ecstatic after meeting the characters because he didn’t know they would speak ‘his language,'” the agency told ABC News.

What’s perhaps most remarkable is that the characters weren’t told about the boy before his arrival, though his family had arranged to have a Disney translator with him during the visit.

According to WZZM-TV, each year, Olive Crest sends foster kids and adoptive families to Disneyland for Foster Care Awareness Month. The name and identity of the child shown in the video hasn’t been released.
